<p>The <b class="package">dicttool</b> package enhances the standard <em>dict</em> command with several new
commands. In addition, the package also defines several &quot;creature comfort&quot; list commands as well.
Each command checks to see if a command already exists of the same name before adding itself,
just in case any of these slip into the core.</p>
<dl class="doctools_definitions">
<dt><a name="1"><b class="cmd">ladd</b> <i class="arg">varname</i> <i class="arg">args</i></a></dt>
<dd><p>This command will add a new instance of each element in <i class="arg">args</i> to <i class="arg">varname</i>, but only if that element
is not already present.</p></dd>
<dt><a name="2"><b class="cmd">ldelete</b> <i class="arg">varname</i> <i class="arg">args</i></a></dt>
<dd><p>This command will delete all instances of each element in <i class="arg">args</i> from <i class="arg">varname</i>.</p></dd>
<dt><a name="3"><b class="cmd">dict getnull</b> <i class="arg">args</i></a></dt>
<dd><p>Operates like <b class="cmd">dict get</b>, however if the key <i class="arg">args</i> does not exist, it returns an empty
list instead of throwing an error.</p></dd>
<dt><a name="4"><b class="cmd">dict print</b> <i class="arg">dict</i></a></dt>
<dd><p>This command will produce a string representation of <i class="arg">dict</i>, with each nested branch on
a newline, and indented with two spaces for every level.</p></dd>
<dt><a name="5"><b class="cmd">dict is_dict</b> <i class="arg">value</i></a></dt>
<dd><p>This command will return true if <i class="arg">value</i> can be interpreted as a dict. The command operates in
such a way as to not force an existing dict representation to shimmer into another internal rep.</p></dd>
<dt><a name="6"><b class="cmd">rmerge</b> <i class="arg">args</i></a></dt>
<dd><p>Return a dict which is the product of a recursive merge of all of the arguments. Unlike <b class="cmd">dict merge</b>,
this command descends into all of the levels of a dict. Dict keys which end in a : indicate a leaf, which
will be interpreted as a literal value, and not descended into further.</p>
<pre class="doctools_example">
set items [dict merge {
  option {color {default: green}}
} {
  option {fruit {default: mango}}
} {
  option {color {default: blue} fruit {widget: select values: {mango apple cherry grape}}}
}]
puts [dict print $items]
</pre>
<p>Prints the following result:</p>
<pre class="doctools_example">
option {
  color {
    default: blue
  }
  fruit {
    widget: select
    values: {mango apple cherry grape}
  }
}
</pre>
</dd>
